UNIVERSAL VALVE.

` To all 'whom jt ma concern:

Be it known t1 t I, WALTER l-l. Birra-.a citizen of the United States, and a resident of North Plainfield, in the county of Somery5 set and State of New Jersey, have made and4 Further and subordinate objects of invention are to provide various other improvements in andv relating to the structure and to particular features of such valves, all

as illustrated in the accompanying drawing, described in the following specification, and

'particularly claimed in the concluding claims.

,In the accompanying drawings wherein the preferred embodiment ofmy invention is illustrated: Figure 1 is a view showing the body portion or casing of my improved valve with the valve disk in place therein,

as seen vfrom a plane indicated by the line 1'1, Fig. 8, looking up, the coverand operating spindle being removed; Fig.v 2 is a view vshowing a section of the entire valve ,plane indicated by the line 2-2, Fig. 1; Fig. 3 is a similar view upon a plane indicated by the line 3-3, Fig; 1 Fig. 4

upon said cover and 23 is an operating spin-` dle for said valvedisk the saine being supported by `a bearing formed in the cover 21 as shown in Figs. 2 and 3. The cover and body portion are held together by bolts or equivalent fastening. means, so that the ,cover may be readily removed for the purpose of varying the position of' the' valve disk relative to the ports which it controls,

to thereby adapt and arrange the valve for f the particular use to which-it is to be put,

as will hereinafter appear. The fact that the valve seat is upon the cover provides for a convenient ie-grinding thereof, the cover being removable without disturbing any pipe connections as all pipes leading to and from the valve connect with o-penings in the body portion or casing, and communicate with the ports in the cover by means of passages formed in the casing and cover as next appears.

The body portion or casing 20 is provided 75 with a pluralityof openings 'as shown at 24, 25, 26, 27 and 28 designed to receive two or more pipes through which' the Huid, the flow of which is to be controlled may flow; the number of pipes, and their location and arrangement, being determined as will hereinafter appear by the particular use to which the valve is to be-put. Such openings as do not have pipes connected with them when the valve is arranged for a given predetermined purpose are closed by plugs as will hereinafter appear. vThe openings 2liv and 25 lead directly into the space inclosedby the valve casing and cover, and the flow of fluid through them is not directly controlled by the valve 22, while the other openings communicate with ports which are opened and closed by said valve to thereby control the flow of iluid through them as next appears.

The cover 21 is provided with three passages 29, 30, and 81 which communicate respectively with the openings 26, 27 vand 28 and which passages terminate `1n 4ports 32, 33 and 34, which ports 100 are controlled by the valve disk 22, whereby Y i the fiow of fluid through said ports and passages 'may be controlled by said valve.

' Theva'lvel disk 2,2 is` providedvwithdiametrically opposite flat bearing surfaces 35, 36 which movein contact with the inner surface of the cover21 and Which when 'over either off`the ports'y 32, 33, 34 interrupt the How of iiuid from the interior of the valve casing therethrourrh, and With a segmental passage 37 cut o :from the interior of the valve ea'singorbodybut through Which a ilow of fluid may occur from either of the ports 32, 33, 34 to and through another of said ports in the various conditions under which 'the-valve may be used. 'A

Oscillat'ory motion is transmitted to the valve disk 22 through the operati'nfr spindle' 23,1the'inner end thereof being made square as .shown and said squared ,portion fitting into a recess 38A of vlike form provided in the said valve'disk.- The end'of the spindle tits somewhaty looselyl in vthe recess 38 so that the valve may bear uniformlyl t-hroughout- .the entire area of its seat even though the axis of the spindle be not precisely at right angles to the valve seat. The spindle 23 is operated byV any suitable operating means connected with the ,outer end thereof., such,

for instance,.as by an arm or lever; no op-` erating means, however, is shown, as the same. obviously forms no partrof the invention to which this application relates.

The operating spindle 23 is provided With a longitudinally extending passage 39 Which may be filled with oil or other lubricant through a plugged fitting 40 at the outer end thereof to thereby provide for lubricating the seat' of the valve disk '22. The oil or kother lubricant Within the passage 39, Will, 35

4as t-he valve is used, ,l Work around the squaredinner end of the said spindle and youtward between the valve disk and its seat therebyilubricating the same; and it is obviously impossible for the lubricant to escape from thev passage 39 Without passing between the valve and its seat. The side Walls of 'the recess 38 are preferably provided with groovesf41 tdfacilitate the flow of oil..

l The valve disk 22 is provided with a projecting arm 42, and the valve casing or body 2O isprOVidedVWit-h a series of'projecting v stops or lugs/43 uniformly'spaced about the matic views Figs. '7 to 13.

trated 1n the `diagrammatic views Figs. 7 to .13..4 `These figures show the valve body or casing 2O and thevalve disk 22 therein, the coverv 21 beingrremoved. The positions of I the ports 32,'33 and 34 are indicated in e5.-

dotted lines to facilitate the understanding The vprincipal of the various uses to Which fmy improved valve may be put are illus-v of the operation of the valve,l these ports being actually located as hereinbefore eX- plained, in the cover.

Figs. 7 and 8 show my valve. arranged as a tWoWayvvalve for controlling the flow of fluid through the pipes 45, 46 leading to and from the valve casing 20. The pipe 45 is shown as extending into the opening 24, although it might as Well be connected at the opening 25, so as to discharge into the valve casing. The valve disk A22 1s so placed 75 that one of thesurfaces 35vvill cover some one of the ports 32, 33, 34 when the arm 42 thereof is midway between tivo of the stopping lugs 43, whichl port- AWill be the one controlled by the valve and Withyivhich the pipe leading from the valve Will be made to communicate. In Figs. 7 and 8 the port 32 is the one controlled, and, When the valve disk is so moved as to uncoverv said port, as shown in Fig. 8, fluid Will flow through said port and the passage 29 and pipe 46. Obviously either of the ports 33 or 34 could be controlled in the same Way, and, in all cases, all npenings except those into which the pipes 45, 46 lead are closed by threaded plugs 47 as shown.

Figs. 9, 10 and 11 show the use of my device as a three-Way valve to control the flow of fluid through the inlet pipe 45 and pipe 49 to any given device, and from that device through the pipes 49, 46. The valve disk is so placed as that the fiat portions 35, 36

cover the ports 33, 34 When the valve is in its middle position. Movement of the valve in either direction Willv uncover the port 33 or 34 according to the direction of motion.

and movement in a reverseY direction Will connect the-port in question with the port 32 through the segmental passage 37 in the valve. As shown in these figures the port 33 and'passage 30 are used to connect with ,the pipe 49, the opening communicating with the port 34 being plugged.

Figs. 12 and 13 shouv mv valve used as a four Way valve to control the tlowof fluid from the inlet pipe '45 through either of the pipes 49, 52 to two devices; and from those devices through the pipes 49, 52 "find '46. The arrangement of the valve is the same as in Figs. 9 to 11, both the ports 34. hoW- ever, being utilized. When the valve is moved into the position shown in Fig. 12, Huid flows through the pipe 45, port 33, passage 30, and pipe 49; and through the pipe 52, passage 31 port 34, segmental passage 37 in the valve, port 32, passage 29 and pipe V43. When the valve is moved into the posivtion shown in Fig. 13, the fluid flows from the pipe 45 to and through the pipe'52; and from the pipe 49 to and through the pipe 46, the manner in which the ports and passages Within the valve register being obvious from the above descri tion. lt will be un erstood that pipe 45 might be connected with the opening 25 if desired; in lwhich case the opening :24 Will be closed by a plug like the plug 47.
